Always Co SUlt an <br /> N'oie: The F-1000 S1101.11d be serviced by qLKIlitled Pei-SOIIS 0111V. <br /> Although the F-1000 is designed to withstand outdoor conditions, a cool, dry location where the unit can be easily <br /> serviced is recommended <br /> •The F-1000 can be mounted on horizontal or vertical runs of pipe (see figure 4, 5 and b) Mounting at the twelve <br /> o'clock position on honzontal pipe is recommended Mounting anywhere around the diameter of vertical pipe is <br /> acceptable, however, the pipe must be completely full of water at all times Sack pressure is essential on downward <br /> flows <br /> •The F-1000 accuracy is affected by disturbances such as pumps,elbows, tees,valves in the flow stream Install the <br /> meter in a straight run of pipe as far as possible from any disturbances The distance required for accuracy will <br /> depend on the type of disturbance <br /> Type Of Disturbance Minimum Inlet Pipe Minimum Outlet <br /> Length Pipe Length <br /> Flange 10 X Pipe 1 D 5 X Pipe I D <br /> rLeuuc.cx i a X ripe i u i D x ripe 1 IJ . <br /> 90°Elbow 20 X Pipe I D 5 X Pipe I D <br /> Two 90'_Elbows�l_ —25-X Pipe-1 D _5_X Pipe I D <br /> Direction <br /> Two 90°Elbows -2 40 X Pipe I D 5 X Pipe I D <br /> Directions <br /> Pump Or Gate Valves 50 X Pipe I D 5 X Pipe I D <br /> a The pipe must be comple ely full at all tunes Air bubbles or air pockets in the `low stream will adversely affect the <br /> reading A small amount of back pressure is recommended in horizontal runs of pipe <br /> •The F-1000 is powered by two AAAbattenes Life expectancy is one year minimum <br /> 4.2 PIPE FLOW STREAM REQUIREMENTS <br /> •The F-1000 accuracy is based on steady,undisturbed flow with afully developed turbulent flow profile Pulsating, <br /> swirling and other disruptions in the flow stream will effect the meter's accuracy <br /> The F-1000 is factory calibrated to f 2%of full scale rate reading When measunng total flow,accumulated error over <br /> time must be considered Accuracy is based on laboratory testing of nominal pipe dimensions Your actual accuracy <br /> will vary based on your actual pipe I D And other installation factors <br /> •There are two basic types of flow profiles,turbulent and laminar(see figure 3) Turbulent flow exists when the <br /> speed of the fluid flowmg in the pipe is nearly constant across the entire width of the pipe This is typical of low <br /> viscosity fluids, like water, flowing at high velocity Laminar flow exists when the speed of the fluid flowing in the is <br /> center of the pipe is greater than the speed of the fluid at the outer edge near the pipe wall This is typical of high <br /> viscosity fluids flowing at low velocity Because the F-1000 is measuring the fluid near the pipe wall only(especially <br /> in larger pipe sizes), a constant flow velocity across the flow stream is required <br />
